Anyone know where it was first said on-panel?

-Jeph!

I have no idea as to the issue numbers but I remember a storyline in Wolverine (or was it Uncanny X-Men? Or X-Men?) in which Jubilee got caught up in some time-travel craziness. It was during this adventure that she learned that her parents were killed because their murderers confused them with their next-door neighbours who also had the same last name.

However, I can't swear that that was the first in-story mention of her last name, it's just the first that comes to mind.
